Application led January 27,

.To @ZZ u'hom it may concern: he it known that il, BERNARD KERN, .l r., a citizen of the llnited States, and a resident of Toledo, in the county of Lucas and State of hic, have invented certain new and useful improvements in Dumping-Wagons; and ll do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same, accompanying drawings, and to the letters and figures of ref-v erence marked thereon, which form a part of Vthis specication. My invention relates to mechanically-operated dumping-wagons of the class adapted either for separate use or for use in connection with street-sweeping machines, threshu ing-machines, or the like for receivingv the sweepings or threshed product thereof; and provision of improved means for automatically dumping or unloading the contents ofY a-wagon or other receiving-receptacle.

llhe mechanism, operation, and arrangement of the parts comprising my invention are fully described inthe, following specification, and shown in the accompanying drawings, in which- Figure 1 is a plan view of my improved machine, with part in horizontal cross-section to show the internal arrangement of the parts. Fig. 2 is a side elevation of the adjustable conveyer at the rear of the machine. Fig. 3 is a detail front View of the conveyer-controlling mechanism. Fig. A is a side elevation of the chain-guiding member shown in Fig. 3, and Fig. o is a transverse vertical section of the receivingbin of my machine.. l

Referring to the drawings, A represents the receptacie or receiving-bin of my invention, and .F1 the front platform, supported upon and made portable by the two :front wheels il and the two rear wheels D. At the rear of the receptacle A is pivotally mounted the adjustable conveyer or carrier by means of which the contents of the receptacle A when deposited thereon, as hereinafter' described, may be transferred to a dump pile or other Mounted on the platform B is an engine F,

which generates power for rotating the shaft 1, which in turn communicates motion to the rear drive-wheels l) for propelling the machine through the medium of the sprockets 2 on the ends of said shaft, the chains 3, and

large sprockets 4C, secured to the inner sides of said wheels.

he lower portion of the bin A dinally contracted and is formed into two trough-like portions 5 by reason of the frame 6 being secured to the bottom of the bin in central longitudinal position, as shown in Fig. 5. Mounted longitudinally in each of the troughs 5 of the bin A in suitable. bearings provided in the opposite ends thereof is a wormwheel 7, which is adapted to feed the matter contained in the receptacle or bin through a suitable opening (not shown) provided in the rear thereof in alinement with said worm-wheels and to deposit it on the adjacent end of the conveyer F. when said conveyor is adjusted in proper position. An endless carrier-apron 8 connects suitable rollers at each end of the conveyer-frame E and is adapted to carry the deposits Vto and discharge them over the free end thereof upon a dumping-pile or in any other suitable place. Fewer is transmitted to the apron 8 through the shaft 9, which is mounted longitudinally within the frame 6, the counter-shaft 10, and the chain 11, said shafts having the meshing' spiral gears 12 mounted thereon and said chain connecting the sprocket-wheels 13 13, which are mounted on the ends of the shaft and the lower roller-shaft 1A of the conveyor, as shown in Figs. 1 and 2. A bevel-gear 15 is mounted on the forward end of the shaft 9 and meshes with the companion bevel-gear 15, from which it receives its power. ',lhe bevelgear 15 is keyed to a sleeve 16, which is mounted loosely on the shaft 1, whereby it is permitted to turn independently thereof and is adapted to receive its power from the engine F by any suitable connection therewith. 'Fo enable the bevel-gear 15 to be thrown into and out of engagement with the gear 15', as it may be desired to operate the conveyorapron 8 or worm-wheels 7, the forward end of the shaft 9 is mounted in an eccentric bushing 9', which bushing has its movement controlled by the lever 17, which has its lower end prou vided with a sleeve surrounding said bushing, as shown in Fig. 3.

The worrn-wheels i 7 have a sprocket-wheel 18 secured to each of their forward ends in transversely alining position with the sprocket-wheel 19, which is mounted on the forward end of the shaft 9 and with each other' and with the sprocket-wheel 19 bythe endless sprocket-chain 20, as shown is longituin Fig. 3, by means of which the wornrwheels ZOO ITO

7 7 are rotated. 14n orderto release the chain 2O from meshing engagement with the sprocket 19, when it is desired to operate the conveyerapron 8 independently of the worms 7 7 for the purpose of freeing said apron of dirt des posited thereon just prior to the stopping' of the rotation of said worms, 1 provide avertically-reciprocatory member 21, which carries an idler-pinion 22 at its lower end for engaging the lower inner side of the chain 2() for tightening the same. A horizontally-disposed transversely-projecting arm 23 is also carried by the member 21 in position to engage the upper inner side of the chain 20 on either side of the sprocket19, whereby said chain may be lifted out of meshing engagement therewith when the member 21 is raised, thereby permitting the sprocket 19 and shaft 9 to have a movement independent of the worm-wheels 7 7. The member 21 is guided in its vertical movement by means of the guidepieces 24 24, through which it passes and which are secured to the front of the bin A, andis retained in adjusted position by means of the. pin 25, which passes through alining' apertures provided therein and in the upper guiding-piece 24. i`

For the purpose of rotatingthe shaft 1 and transmitting motion to therear drive-wheels D for propelling the machine by powerl generated by the engine F, I provide a clutchsleeve 25, which is feathered to theshaft 1 and adapted to be moved longitudinally thereof by an oscillation of the lever 26 to have its side engage in any suitable manner with the .contiguous end of the driven sleeve '16, whereby the shaft 1 is rotatable.

The operation of my invention is as follows: When it is desired to unload the contents of the bin A, which have beenA deposited therein' in any suitable manner, the lever 17, connecting with the eccentric bushing 9' on the shaft 9, is moved in the proper direction to throw the bevel-gear 15 in meshing engagement with the `driving bevel-gear 15 on the revolving sleeve 16, thereby communicating motion to the shaft 9 and through it to the counter-shaft 10 and conveyer belt or apron 8, the latter being first adjusted to the desired slant.. The worm-wheels7 7 are then set in motion by the lowering of the member 21 to permit the sprocket-chain 20, connecting the sprockets 18 18, to engage the rotating sprocket-wheel 19 on the shaft 9, thusl causing a steady feed of the contents of the bin A to fall upon the rear end of the conveyer-apron 8 and be discharged by it as desired. Should the unloading operation be stopped before the contents .of the bin A have been entirely discharged therefrom, the rotation of the worms 7 7 should first be stopped by the raising of the chain 20 from engagement with the drivingsprocket 19, so as to stop the feed of vsaid worms and at the same time permit the conveyer-apron to revolve to entirely discharge tents of the receptacle thereon,

in advance ofthe receptacle or bin, a counter-A its load. The propelling accomplished by throwing the clutch-sleeve 25 into engagement with the contiguous notched end of the sleeve `16, thus communicating motion to the spmcket -chains 3 and drivewheels D.-

It is obvious that such changes in theform, proportion, and minor details of construction of the vparts as fairlyv fall within the scope of my invention may be made without departing fromrthe -spirit or sacrificing any of the ad-` vantages thereof.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, is Y 1. In a machine of the class described, the combination of a receptacle-or bin having an adjustable conveyer pivotally mounted to the rear .ofthe receptacle or b in and having an endless conveyer-apronv thereon, .one or more wormwheels mounted longitudinally in the bottom of 'saidy receptacle or bin vand having their rear ends terminating adjacent'to the lowerend of the conveyer for. discharging the cona driving-shaft shaft disposed longitudinally of the receptacle of the machine is' or bin and adapted to communicate motion from the driving-shaft'to the conveyer-apron,

connection between said counter -shaft andv worms, and mechanism adapted to be adjusted 'I A to cause saidworm-wheels and conveyer-apron to operate in unison or` said conveyer-apron to operate alone. v f v 2. In combination, a portable receptacle having its lower portion contracted to form a trough, an adjustable conveyer-frame secured to the rear of the receptacle and having an endless conveyer-apron thereon, power means in advance of said receptacle, a shaft mounted longitudinally of the receptacleY and adapted to-receive rotation from said power means, means connecting said shaft and conveyerapron for operating the latter, a plurality of feed-worms in said receptacle for feeding the contents thereof to said conveyer., wheel secured to each feed-worm and to said shaftvin alining position, an endless chain connecting said sprocket-wheels, and vmeans for throwing said chain into or out of engagement with the sprocket-wheel on said shaft for the purpose described.
